SNOW-MELT'ING MACHINE.

SPECIFICATION forming part of Letters Patent No. 541,709, dated June 25,1 895.v

Application filed February 19, 1895. Serial No. 538,933. tNo model.)

.Snow-Melting Machine, of which the following is a full, clear, andexact description.

The object of the invention is to provide a new and improved snowmelting vmachine, more especially designed to be drawn through thestreets of cities and like places, and arranged to quickly melt thesnow.

The invention consists of certain parts and details and combinations ofthe same, as will be fully described hereinafter and then pointed out inthe claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in whichsimilar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a sectional side elevation of the improvement on the line ll of Fig. 2. Fig. 2 a sectional plan viewof the same on the line is 2 2of Fig. 1. Fig. 3 isa plan view of the fur nace with the cover removedand one of thek grates partlywithdrawn, and Fig. 4 is a sectional sideelevation of the same in a different position. p

The improved snow melting machine is provided with a wheeled vehicle A,adapted to bedrawn or driven through the streets or other places inwhich the snow is to be melted. This vehicleAis provided in its bottombetween the front and rear wheels with a chamber B, open at the bottomand extending close to the sur` face of the street, as indicated in Fig.l. In

` the front end of the chamberB is arranged a revoluble brush C forsweeping the snow from the street, into the said chamber B. Thisrevoluble brush C is connected by a belt D with a pulley on an engine E,supported on the vehicle A, and driven by steam from a boiler set in thevehicle, or by other suitable motive power. In the top of the chamber Bis arranged a down-draft furnace F, provided with a re box F', arrangedtransversely in the chamber B and journaled at its closed ends bytrunnions F2 in the sides of the vehicle A. A slidab-le and removablegrate F3 is arranged in the bottom of the said tire box F', and asimilar grate F4 is arranged in the top thereof, so that the fire box,when turned upside down, has a grate' both on the top and l on thebottom; andtbetween the grates is con tained the coal Or other fuel tobe burned.

In order to hold the fire box F in proper position, as shown in'Fig. l,I provide va suitable fastening device, preferably in the form of atransverse rod G, adapted to be passed through staples G in the Yvehicle A, and through a staple F5 in the side o f the fire box F. Whenthe rod G is withdrawn, the box can be conveniently turned, to bring thelowermost grate tothe top andthe upper grate to the bottom, as will bereadily understood by reference to Fig. 4.

In order to introduce the fuel, the uppermost grate is pulled out, asindicated in Fig. 3, so as to permit of charging the already burningfuel with a fresh supply of coal. The top of the fire box F above theuppermost grate is adapted to be closed by a cover F6, connected at oneend by a exible pipe H with a blower I, driven by a belt J from theengine E.

Now, it will be seen thatwheu the engine is in motion, the blower I isactuated, and forces air through the pipe H and cover F6, into andthrough the fire box F in a downward direction, so that propercombustion of the fuel in the lire box is obtained, and at the same timethe heat is forced through the lowermost grate F3 into the chamber Bincontact with the snow thrown into the chamber by the brush C. The snowis thus subjected to a high degree of heat and instantly melted,

to then run into the gutter or to be sweptinto the same by followingbrushes if necessary.

A chimney B in the rear end of the chamber B, permits the escape 0fgases from the I claim as new and desire to secure by Letters Patent-ICO adapted to supply air thereto, substantially as set forth.

3. The combination of a heating chamber having a transverse shaft, afurnace rotatably mounted in the heating chamber and provided withlongitudinally movable grates at its opposite sides and having means forlockin g it to said transverse shaft when set to the required position,a cover plate located in the heating chamber and adapted to close oneside of the furnace, a blower, and a pipe connectingthe blower with thecover of the heating chamber, substantially as set forth.
